Method and apparatus for handling qoe report in a secondary node in a wireless communication system

Abstract

A method and apparatus for handling QoE report in a secondary node in a wireless communication system is provided. An SN transmits, to a UE, a configuration for Quality of Experience (QoE) measurement. The QoE measurement is initiated by an Operations, Administration and Maintenance (OAM) and/or a master node (MN). An SN receives, from the UE, a QoE report based on the configuration. An SN determines whether to forward the QoE report to (i) a Trace Collection Entity (TCE) and/or a Measurement Collection Entity (MCE) and/or (ii) the MN, based on which entity among the OAM and/or the MN initiates the QoE measurement. An SN forwards the QoE report based on the determination.

1 . A method performed by a secondary node (SN) in a wireless communication system, the method comprising,
 transmitting, to a UE, a configuration for Quality of Experience (QoE) measurement, wherein the QoE measurement is initiated by an Operations, Administration and Maintenance (OAM) and/or a master node (MN);   receiving, from the UE, a QoE report based on the configuration;   determining whether to forward the QoE report to (i) a Trace Collection Entity (TCE) and/or a Measurement Collection Entity (MCE) and/or (ii) the MN, based on which entity among the OAM and/or the MN initiates the QoE measurement; and   forwarding the QoE report based on the determination.   
     
     
         2 . The method of  claim 1 , wherein the QoE report is forwarded to the TCE and/or the MCE, based on that the OAM initiates the QoE measurement. 
     
     
         3 . The method of  claim 1 , wherein the QoE report is forwarded to the MN, based on that the MN initiates the QoE measurement. 
     
     
         4 . The method of  claim 3 , wherein the method further comprises,
 transmitting, to the MN, an Xn message including a container,   wherein the QoE report is included in the container.   
     
     
         5 . The method of  claim 1 , wherein the QoE report includes information informing destination of the QoE report. 
     
     
         6 . The method of  claim 5 , wherein the QoE report is forwarded to the destination. 
     
     
         7 . The method of  claim 1 , wherein the QoE report includes an explicit indication or a specific identifier (ID) of the UE. 
     
     
         8 . The method of  claim 7 , wherein the method further comprises,
 determining which entity among the OAM and/or the MN initiates the QoE measurement, based on the specific ID of the UE.   
     
     
         9 . The method of  claim 1 , wherein the QoE report includes a QoE service type. 
     
     
         10 . The method of  claim 9 , wherein the method further comprises,
 determining which entity among the OAM and/or the MN initiates the QoE measurement, based on the QoE service type.   
     
     
         11 . The method of  claim 1 , wherein the QoE report includes an internet protocol (IP) address of the TCE and/or the MCE. 
     
     
         12 . The method of  claim 11 , wherein the QoE report is forwarded to the TCE and/or the MCE directly. 
     
     
         13 . The method of  claim 1 , wherein the method further comprises,
 receiving, from the UE, a Radio Resource Control (RRC) message including a container,   wherein the QoE report is included in the container.   
     
     
         14 . The method of  claim 1 , wherein the QoE report is received from the UE via a Signalling Radio Bearer (SRB). 
     
     
         15 . The method of  claim 1 , wherein the UE is in communication with at least one of a user equipment, a network, or an autonomous vehicle other than the UE. 
     
     
         16 . A secondary node (SN) configured to operate in a wireless communication system, the SN comprising:
 a memory; and   at least one processor operatively coupled to the memory, and configured to:   transmit, to a UE, a configuration for Quality of Experience (QoE) measurement, wherein the QoE measurement is initiated by an Operations, Administration and Maintenance (OAM) and/or a master node (MN);   receive, from the UE, a QoE report based on the configuration;   determine whether to forward the QoE report to (i) a Trace Collection Entity (TCE) and/or a Measurement Collection Entity (MCE) and/or (ii) the MN, based on which entity among the OAM and/or the MN initiates the QoE measurement; and   forward the QoE report based on the determination.   
     
     
         17 . The SN of  claim 16 , wherein the QoE report is forwarded to the TCE and/or the MCE, based on that the OAM initiates the QoE measurement. 
     
     
         18 . The SN of  claim 16 , wherein the QoE report is forwarded to the MN, based on that the MN initiates the QoE measurement. 
     
     
         19 . The SN of  claim 18 , wherein the at least one processor is further configured to,
 transmit, to the MN, an Xn message including a container,   wherein the QoE report is included in the container.   
     
     
         20 - 32 . (canceled) 
     
     
         33 . A method performed by a wireless device in a wireless communication system, the method comprising,
 receiving, from a secondary node (SN), a configuration for Quality of Experience (QoE) measurement,   wherein the QoE measurement is initiated by an Operations, Administration and Maintenance (OAM) and/or a master node (MN);   transmitting, to the SN, a QoE report based on the configuration,   wherein the QoE report is forwarded to (i) a Trace Collection Entity (TCE) and/or a Measurement Collection Entity (MCE) and/or (ii) the MN, based on which entity among the OAM and/or the MN initiates the QoE measurement.
